Alkaline nutrition is a subject that has become increasingly popular in recent years and is open to research, and it frequently appears in academic studies both on social media and in the literature.
The basis of the alkaline diet is based on the principle of consuming less of some foods and more of some foods. . Alkaline diet; reducing the consumption of meat, dairy products, eggs, whole grains and processed foods; It recommends increasing the consumption of vegetables, fruits and legumes. (About 1/4) In the alkaline diet, consumption of sugar, salt and meat is not completely prohibited, only its amount is reduced. It is advocated that organic foods should be preferred instead of foods exposed to pesticides, antibiotics and hormones in acid form. 1 liter of alkaline water should be consumed for every 20 kg. It is stated that with such a diet, weight loss and optimal health will be improved in the body as a result of reducing acid. Although the evidence regarding weight loss is quite low, it is said that it may be beneficial for bones and kidneys with the nutrients it contains.
Those who do not support the alkaline diet criticize the restrictive aspects of the alkaline diet and emphasize that it may lead to eating disorders such as malnutrition or orthorexia.
PH CONCEPT:The pH in the body is graded from 1 (most acidic) to 14 (most alkaline), neutral pH is 7 and the optimal pH in the blood is between 7.2-7.4 p>
If people's diets do not contain enough calcium, magnesium, potassium and other acid-buffering minerals, these minerals are withdrawn from the stores of tissues such as bone, liver and heart and can cause serious problems. Generally, individuals are poor in magnesium, potassium and fiber; The diet is rich in saturated fatty acids, simple sugar, sodium and chloride. This type of nutrition reduces renal acid-base regulatory functions and as a result, diet-induced metabolic acidosis increases. Low carbohydrate and high protein diets cause changes in the urinary system by increasing acid load; It causes changes in the blood and pH level. Thus, while urinary magnesium, citrate and pH levels decrease; The level of urinary calcium, undissolved uric acid and phosphate increases. All these results increase the risk of kidney stone formation.
Alkali It has been found that elevated bicarbonate (without potassium) may attenuate bone loss in healthy elderly people A systematic review article on the current literature found evidence that an alkaline diet is not protective against dietary acid load for bone health in osteoporosis
Excessive dietary protein intake creates high renal acid load; If alkaline-rich foods or nutritional supplements are not taken, the buffering system cannot be activated and the resulting acid load reduces bone density.
As a result;
-
It may be more accurate to increase the amount of fruit and vegetable consumptionthan to reduce protein intake.
-
Foods considered acidic and alkaline have different effects on the body.
-
Especially their positive effects on bone, calcium metabolism and acidosis have been observed.
-
Although studies continue, there is no clear information supporting alkaline nutrition, and there are debates.
-
Since there are advocates and opposing views, more research and clarification of the issue is needed
